Well, nobody got eaten, but clearly something happened during the night:
It's nothing my trusty friend, Net, can't fix.
I wonder why he escaped? Usually, it takes something very frightening to make them try to jump the fence. They like staying home, I think.
P.S. Later on now-- I've been wondering all day about how that duck got out of the fence. It's an electric fence, and it holds the ducks in even when it's turned off. But it was on. And when I turned it off in the morning, the duck wanted to get back in, but needed help to do so. What a mystery!
